Don't succumb to the fear...
Obviously you've moved beyond weed. You've danced with the damsel named Mary Jane for a bit, and found she's fun to spend some time with, but she's not the kinda girl you want to spend the rest of your life with.
This is a good life lesson--It takes a lot of time and practice to find, "the one." Just because you've tried once and it didn't work out doesn't mean you should give up.
To be fair, Marijuana is the scum-drug of the earth. Mary Jane is like the girl from the trailer-park you date in high school, and you think you're going to spend the rest of your life with her. You spend your entire junior and senior years making plans for the future. Then, just when everything is perfect, and you're choosing names for your future children, it's time to go away to college...
You get to your separate destinations... You share a few phone calls. You try to maintain a passionate, long-distance relationship with Mary Jane, but it's difficult. You begin to realize Mary Jane isn't so smart. She's not even that pretty. She's just some chick that paid attention to you when no one else would.
And then you start to realize there are a whole buncha other hot girls, or in this case, drugs, available. They're everywhere: The sorta cute, interesting girl known as, "mushrooms." The edgy, chaotic hottie known by the nickname, "LSD." The girl so beautiful and controlling you need ten grand in the bank just to go on a date with her... we'll call her, "Cocaine." And let's not forget the woman completely capable of ruining your life within a day and a half..."heroin."
All fun girls. For sure. You just need to figure out which one is right for you.
The point is, you need to explore all of your options.. and you're obviously ready for the next level.
You should begin dating all of these girls--trying every drug you can get into your body--to see which of them is the right fit for you.
I'd suggest moving up to mushrooms, and then LSD. When those get boring, or make you "crazy," it's obviously time to start sniffing, snorting and freebasing. Huff some glue if you need to. Lick a toad. Take an adventure into the worst neighborhood you can find, and buy crack from a stranger in an alley. Life is worth living, man!!!
Before you know it, you'll be able to cook drugs in the comfort of your own home. You'll be the master of your domain. You'll be the model of self-control, paranoia be damned.
That which doesn't kill you will only make you Stronger. Better. Faster. All that.
It's time for you to soldier on through the darkness, and come out on top with a head full of acid, a nose full of cocaine, and a needle at the ready--to pluck your flesh and take you through the next level of evolution.
